syslog-bunyan-logger

bunyan-syslog is a stream for bunyan that consumes raw records from bunyan and sends them to a syslog server.

Installation

npm install syslog-bunyan-logger

Usage

var bunyan = require('bunyan');
var bsyslog = require('bunyan-syslog');

var log = bunyan.createLogger({
	name: 'foo',
	streams: [ {
		level: 'debug',
		type: 'raw',
		stream: bsyslog.createBunyanStream({
			type: 'sys',
			facility: bsyslog.local0,
			host: '192.168.0.1',
			port: 514
		})
	}]
});

log.debug({foo: 'bar'}, 'hello %s', 'world');

That's pretty much it. You create a syslog stream, and point it at a syslog server (UDP by default; you can force TCP by setting type: tcp in the constructor); default is to use facility user and a syslog server on 127.0.0.1:514. Note you must pass type: 'raw' to bunyan in the top-level stream object or this won't work.

Mappings

This module maps bunyan levels to syslog levels as follows:

+--------+--------+
| Bunyan | Syslog |
+--------+--------+
| fatal  | emerg  |
+--------+--------+
| error  | error  |
+--------+--------+
| warn   | warn   |
+--------+--------+
| info   | info   |
+--------+--------+
| *      | debug  |
+--------+--------+
